Description

Technical Field

[0001] This utility model relates to the field of gear assembly equipment technology, specifically a gear assembly auxiliary fixing device. Background Technology

[0002] Gears are transmission components of industrial machinery. During gear processing, a blank of the same thickness as the gear is first cut from a steel bar, and a groove is cut on the front of the gear. Then, holes need to be drilled in the groove and the blank. These holes not only reduce the weight of the gear, but also allow coolant to flow during the gear processing, so as to achieve the purpose of rapid cooling of the gear.

[0003] During the assembly and installation of gears, they usually need to be limited to ensure that the relative position of the gears does not change during subsequent assembly. The current gear limiting and fixing method mainly uses a snap-on clamping method to fix the gears. However, snap-on clamping may loosen due to operator error during actual fixing. At the same time, snap-on limiting and fixing is not firm. Under high-intensity vibration, the gear may deviate from the assembly position, thus affecting the actual gear assembly accuracy. Utility Model Content

[0004] The purpose of this utility model is to provide a gear assembly auxiliary fixing device. By optimizing and improving the gear limiting and fixing structure, the installation accuracy during gear assembly is improved and the gear limiting capability is strengthened, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gear assembly auxiliary fixing device includes a fixing base and a fixing plate fixed to the bottom of the fixing base. It is characterized by further including a fixing sleeve and a U-shaped sleeve. The fixing sleeve and the U-shaped sleeve fix the gear. The U-shaped sleeve cooperates with the fixing sleeve. The fixing sleeve is fixed to the fixing base. The fixing base has a sliding groove and symmetrically opened slots. The two ends of the U-shaped sleeve are slidably connected to the slots. Both ends of the U-shaped sleeve have retaining grooves. A magnet is fixedly connected to the bottom of each retaining groove. The fixing base has a sliding groove, and the slots have clamping mechanisms for clamping the two ends of the U-shaped sleeve.

[0007] As a further embodiment of this utility model: the clamping mechanism includes a push plate, and the push plate is provided in two sets. The two sets of push plates are symmetrically rotatably connected to the inner wall of the slot. A torsion spring and an air bladder are fixedly connected between the push plate and the inner wall of the slot. A sealing groove is symmetrically provided on the inner wall of the slot. A clamping block is slidably connected in the sealing groove. A conduit is connected between the air bladder and the sealing groove.

[0008] As a further improvement of this utility model, the fixed sleeve has limiting holes at both ends that cooperate with the ends of the U-shaped sleeve.

[0009] As a further improvement of this utility model, the fixing sleeve and the fixing base are fixedly connected by multiple sets of connecting rods.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: during the process of inserting the U-shaped sleeve into the slot, the push plate is squeezed, and the torsion spring cooperates with the push plate to fix the two ends of the U-shaped sleeve. The push plate rotates and squeezes the airbag, and the air in the airbag is forced into the sealing groove along the guide tube. The pressure in the sealing groove increases, causing the clamping block to clamp the side wall of the U-shaped sleeve, which effectively improves the limiting ability during the gear installation and assembly process.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Please see Figure 1-5This embodiment provides a gear assembly auxiliary fixing device, including a fixing base 1 and a fixing plate 101 fixed to the bottom of the fixing base 1. The device further includes a fixing sleeve 2 and a U-shaped sleeve 3. The fixing sleeve 2 and the U-shaped sleeve 3 fix the gear. The U-shaped sleeve 3 cooperates with the fixing sleeve 2. The fixing sleeve 2 is fixed to the fixing base 1. The fixing base 1 has a sliding groove 6 and symmetrically opened slots 4. The two ends of the U-shaped sleeve 3 are slidably connected to the slots 4. Both ends of the U-shaped sleeve 3 have a retaining groove 301. A magnet 302 is fixedly connected to the bottom of the retaining groove 301. The fixing base 1 has a sliding groove 6, and the slots 4 have a clamping mechanism for clamping the two ends of the U-shaped sleeve 3.

[0020] Furthermore, the clamping mechanism includes a push plate 401, which is provided in two sets. The two sets of push plates 401 are symmetrically rotatably connected to the inner wall of the slot 4. A torsion spring 403 and an airbag 402 are fixedly connected between the push plate 401 and the inner wall of the slot 4. A sealing groove 5 is symmetrically provided on the inner wall of the slot 4. A clamping block 501 is slidably connected in the sealing groove 5. A conduit 502 is connected between the airbag 402 and the sealing groove 5.

[0021] Furthermore, the fixed sleeve 2 has limiting holes 201 at both ends that cooperate with the two ends of the U-shaped sleeve 3.

[0022] Furthermore, the fixing sleeve 2 is fixedly connected to the fixing base 1 by multiple sets of connecting rods 202.

[0023] The specific working steps of this device are as follows:

[0024] The worker places the gear to be assembled between the fixing sleeve 2 and the U-shaped sleeve 3, and then inserts the U-shaped sleeve 3 into the slot 4 for limiting and fixing. During this process, the slot 4 will squeeze the push plate 401, which can fix both ends of the U-shaped sleeve 3. At the same time, the push plate 401 rotates and squeezes the air bag 402. The air in the air bag 402 is forced into the sealing groove 5 along the guide tube 502. The pressure in the sealing groove 5 increases, thereby clamping the clamping block 501 to the side wall of the U-shaped sleeve 3, effectively improving the device's ability to limit the assembly of gears.
